Ozkan， et al.， used point source method to establish seepage flow model for inclined shaft in top and bottom closed infinite homogeneous formation in Laplace space and bottom hole pressure response of inclined shaft is obtained by Laplace numerical inversion calculation. Along with gradual maturity of directional well technologies， fault block oil reservoir development through inclined shaft method is more and more common. However， there is lack of corresponding well test theoretical charts at present， which brings about difficulties for well test in fault reservoir. Applied are Duhamel superposition principle， mirror image principle and Stehfest inversion algorithm to establish inclined well test model for top and bottom closed tabular fault reservoir and solve it， considered are effects of well reservoir and cuticular layer on dimensionless pressure and pressure derivative curve of inclined shaft， analyzed are seepage characteristics and influence factors of such reservoir inclined well， which can provide a theoretical basis for inclined well test interpretation in the fault reservoir.
